To all whom it may concern:

Be-it known that I, EGBERT H. GOLD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ventilators for Railway-Cars, of which the following is a specification.

My invention relates railway cars of the to ventilators for sort which are arranged outside of the car, usually on the side wall of the clear story, and are so formed as to produce a draft, induced by the movement of the car, which operates to suck the foul air out of the car.

The invention. has for one of its ohjc:ts

to provide an improvement upon or an at tachment for ventilators of this type which will prevent or diminish back draft of outside air into the car. Such back draft'into the car is likely to occur when the car is standing still and the wind is blowing against the side of the car. The ventilators of this type which have been heretofore used are not constructedto preventthis. My invention also tends to prevent dust and cinders from entering the car through the ventilator.

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is a front elevation of a ventilator of known type provided with the imof my invention; Fig. 2, a view, 1 perspective, of the attachment shown in Fig. 1; Fig. 3, a sectional View of ig. 1; Fig. l, a fragmentary cross sectional view of the top of a railway car showing the form of ventilator illustrated in Figs. 1 to 3 inclusive, attached to a clear story; Fig. 5, a view similar to Fig. 4 showing a ventilator of the same general type as that shown in the preceding figures but improved in respect to the form of the cowl or hood; Fig; 6, a side elevationof an improved form of ventilators, theparts b6- ing in section, and Fig. 7 is a front elevation of the same.

. Likecharacters of reference indicate like parts in the several figures of the drawings.

Referring to the drawings, 25 (Figs. t

. and 5) designates the body of the car, 26 the deck and 27 the clear story, the latter being provided with the usual windows 28.

In 'Figs. 1 to 4 inclusive I have shown a ventilator comprising a hood or cowl 29 formed with flanges 30 for attachment to the clear story of the car. The cowl, tapered from back to front, is closed on the top and sides and formed with an opening at the front and under side. V cntilators consist-- ing of cowls or hoods of this configuration have been'used for ventilating railway cars prior to my invention. When attached to the side of a car, for example, over one of the clear story windows or ventilating openings, the movement of the car produces a draft over the opening in the cowl which sucks the foul air out of the car. One objection to a ventilator of this sort is that when the car is standing still, if the wind happens ,to be blowing in a direction toward the opening of the ventilator, it will enter the car through the ventilator producing unconifm'table drafts and perhaps reducing the temperature of the car over much if the weather .is cold. My invention.provides an improvement which in a very great measure obviates this objection without in any way affecting the operation of the ventilator when the car is in motion. The improvcnient consists in arranging a deflecting element in front of the discharging opening of the ventilator of such a character as to prevent a direct back draft of cold air through the ventilator without, however, closing the opening. The form and construction of the deflecting element may be varied. I prefer to construct the deflecting element substantially as shown in Figs. l to 4, in which 31 designates a plate formed with a plurality of transverse slots and with a plurality of lips or flanges 33 extending downwardly over the slots. For convenient attachn'lent to the cowl the plate 30 is formed with flanges 34 on the sides and a flange 35 at the upper outer end. Bolts 36, or other suitable means, may be employed for securing the deflecting plate to the cow]. It is not essential that the deflecting plate should be inade separate from the cow]. If the plates are so made they may be attached to ventilators of the sort described which have been installed without being provided with the deflecting platis over their dis charge opening.

It will be seen that the deflecting element above described effectively prevents the wind from. blowing into the car through the ventilator when the car is at a. standstill. It does not in any way affect the operation of the ventilator when the catis in motion. On the contrary. it tends to improve that the Q car.

As stated, the eowls of ventilators of'the type: here concerned- Qareusually tapered.

ward endof the ventilator so as to-soflfaras possible prevent back drafts of air-into- Obviousl however, this tapering oithe cowl diminishes the strength of the.

draft induced by the movement of; the ear and proportionately diminishes the force fot the suction lay-means of which the foul air: is withdrawn from the car. By providing a deflecting elementover' the discharge opening'of or the wind blowing into the car is elimi- "hated it is possible to change the contour of the-cowl so as to get a stronger suction.

With the; discharge opening protected by a deflecting element such. aatliat above described the size 'andcontour of the opening become unimportant. I "in Figs. 5 to 7 inolusivel have shown an improved form of cowl which is much more eifective as a ventilator than the form shown in the preceding figures. The cowl consists of a top 37 which is of substantially uniform width. from-back to front, sides 38, which are preferably concave, and- ,attachin the front an under side isprovided with adeflecting plate or element the same general principle as. the deflecting plate shownin- Fig, 2. Additionally Iprefor to provide the cowl with the upstanding and outstanding wings 40 at the intersec tion between the top and sides. The purpose of the, wings is to increase the amount of air which is intercepted by the ventilator when the car is in motion and thereby increase the draft over the discharge opening.

With the cowl of the ventilator so formed the sides of the the air is pocketed between over the edge car and; a draft produced the 'v lentilator so that the danger 39 which may be made on mosses of the discharge opening which has a much greater velocity than'would be the case if "the side of the cowl against which the air "imp nges were oblique the movement of the car, as n thetapered formof c0wl,-instead of standing at right angles thereto. I "While I have illustrated my invention in certain preferred embodiments it will be understood that further modifications might be made without departure from the invention. Therefore I do not limit myself to the enactforms and construction shown and described, except as the same are made spe- .eific limitations in certain of the claims; my purpose being to claim both broadly and narrowly whatever patentable novelty the invention may possess in view of the state of the art. I

' I claim:

-1. A ventilator for a railway car, or the like, consisting of a cowl having an imperforate top, imperforate lateral air-collecting faces extending inwardly and downwardly from the top, an'inner side adapted and an open'front and underside provided 'with'a slatted structure comprising a plurality of parallel transversely extending downwardly projecting slats. v

2. A ventilator for a railway car, or the like. consisting of a cowl having an imperforate top, imperforate' lateral air-collecting faces extending inwardly, and down- \vardly from the top, an inner side adapted to communicate with the interior of the car, an open a slatted structure comprlsing a plurality Kof parallel transversely extending down- Qivardly projecting slats, and wings projecting obliquely upwardly and outwardly from the intersections of thetop and lateral faces.
